You have a few obstacals you would need to overcome trying to read an external SATA drive in a usb caddy using only a notebook and DOS.
1. You need DOS drivers for USB. They are flaky at best and sometimes chipset specific.
2. If the drives are NTFS, you would need a utility like NTFSDOS. (DOS cannot natively read an NTFS partition)
3. You would need to create a bootable cd including these drivers, utility and spinrite all on one disc.
4. If the drive itself is physicly damaged enough to where it wont spin-up or the read-head is toast, you won't get anything from it anyways.
Your best bet is to install the drive in a desktop that either supports SATA or use a PCI card in a desktop as Enthusiast has suggested.
